In this study, the design and fabrication of petal-like NiCo/NiO-CoO metal/metal oxides with a rational composition embedded in 3D ultrathin nanoporous carbon composite (NiCo/NiO-CoO/NPCC) is demonstrated. This nanocomposite is synthesized by a two-step procedure involving preparation of bimetallic MOFs by partially substitution of Ni2+ in the Ni-MOF structure by Co2+ (Ni-Co/BDC [BDC = 1,4-Benzene dicarboxylic acid]) and applying a direct carbonization process in the N2 atmosphere at 900 °C. The prepared nanocomposite was used directly as a non-precious electrocatalyst for methanol oxidation reaction. In comparison to the monometallic metal/metal oxides distributed in nanoporous carbon composite (Ni/NiO/NPCC and Co/CoO/NPCC), excellent electrochemical performance of the mixed metals/metal oxides NiCo/NiO-CoO/NPCC was observed toward the anodic oxidation of methanol. This novel multi-component composites are believed to demonstrate good electrocatalytic activity and suitable stability towards the methanol oxidation.

Research in the Electrochemical Research Laboratory, led by Prof. Shahrokhian, is focused on design, fabrication, development and application of electrochemical sensors and biosensors based on chemically modified electrodes for the trace analysis of pharmaceutical and biological species. The objective is to design novel modified electrodes for electro analytical determinations with good efficiency and acceptable performance. The fabrication of the nanostructured modified electrodes using various nanomaterials and nanocomposites for application in electrochemical energy conversion and storage devices (fuel cells and supercapacitors) is another active area in the research group.
